Simple answer to the lower usage. Remember as a kid, your mom always yelling at you to go outside and play on nice days, or stay in on wet nasty days? Well, nice days are coming to an end, so we are starting to stay in and play.

Yea I know but as a kids mom always yelling at us to go outside and play and we wanted to stay in, and on nasty days she wanted us to stay in we wanted to splash, build snow men? You know just the opposite.
